Trees absorb poisonous carbon-di-oxide and produce. oxygen and thereby maintain a ecological balance. But owing to deforestation, the amount of carbon-di-oxide is increasing day by day. Consequently, various natural calamities such as flood, drought, cycione etc. are occurring very often on earth. The world is getting warmer and the sea-level is rising. If this continues, many low lying countries will go under water in future. All living animals and birds will not find any food or shelter to live in. It is high time we stopped deforestation.
